The film doesn't skimp on special effects, but the story and dialogue are wooden.

The dialogue in "Jurassic World" is nothing to write home about — surprise, surprise — but it is telling.

"No one's impressed with a dinosaur anymore," one character says near the beginning of the film. She's talking about visitors to Jurassic World, the theme park built from the ashes of Jurassic Park. But that's the obstacle the filmmakers face, too, right?

When Steven Spielberg's "Jurassic Park" debuted in 1993, seeing a velociraptor whiz by or a T-Rex open his jaws and roar, looking for all the world like real dinosaurs, was stunning. Truly, there hadn't been anything like it before, that kind of realism with such fantastic subject matter, and there couldn't have been a better director than Spielberg to bring it to life.

But now it's 22 years later, both in real life and in the time frame of the film, and director Colin Trevorrow and the team of screenwriters acknowledge with that line the challenge they face, both in the movie and out. A generation of audiences has seen it all before.

Or as they say in the movie, "Consumers want them bigger, louder, more teeth."

At least on that front, "Jurassic World" gives the people what they want.

While customers still flock to the theme park, where they can see more and bigger dinosaurs — kids ride some in one attraction — growth isn't meeting projections. We learn this from Claire (Bryce Dallas Howard), the ice-queen manager who is evidently lacking in any form of human emotion.

This gets at another telling line in the film: "Nothing in Jurassic World is natural."

This includes character development.

To boost attendance, the park's resident scientific genius, Dr. Henry Wu (BD Wong, the lone holdover from the first film), has come up with a new dinosaur, or something like it: Indominus Rex, a genetically engineered creature whose origins are kept a secret. But what's clear is that it is designed to be bigger and badder than anything that's ever come before.

What could possibly go wrong?

If you have to ask, you probably need to see more movies. Everything! Since Mary Shelly dreamed up "Frankenstein" all this god-playing business goes south and in a hurry, and "Jurassic World" is no exception.

To complicate matters further, Claire's nephews Zach (Nick Robinson) and Gray (Ty Simpkins) are visiting the park, but she's been too busy to pay attention to them. But that's OK, it's not like a vicious, dangerous, thinking dinosaur is going to escape or anything. …

Oh. Wait.

Luckily Masrani (Iffran Khan), the park's owner, has hired Owen (Chris Pratt), a former Navy man who has been working to train, sort of, the velociraptors. Pratt's great, but here he is your classic Voice of Reason, pitted against the scheming Hoskins (Vincent D'Onofrio) who wants to weaponize — yes — the velociraptors. Like most of the characters they're cardboard cutouts, meant to suggest action-movie archetypes instead of real people.

The exception to this — and I may be giving him too much credit just because I think he's so funny — is Jake Johnson as Lowery, the resident nerd who handles the high-tech observation of the dinosaurs. He seems like a real guy, whether it's acknowledging that wearing an original Jurassic Park T-shirt might not be in such good taste or coming up short in one of the all-time great would-be romantic moments ever (really).

But Lowery, like the rest of the humans, is just a distraction. The dinosaurs are the attraction here, both at the park and in the movie. Trevorrow, whose only other feature is the terrific indie film "Safety Not Guaranteed" (which featured Johnson), knows this and doesn't shy away from it. He's kind of like Claire and Masrani, after all — he needs to attract paying customers.

Thus we get action-packed set pieces and people-chomping and narrow escapes and a few funny one-liners. It all culminates in a finale that is ridiculously over the top in a not entirely bad way. Although remember the complaints about how absurdly destructive the final battle between Superman and General Zod was in "Man of Steel?" Trevorrow seems to have constructed his climactic battle for those who thought that fight was far too subtle.

Look, let's not kid ourselves. Every third person on the planet will go to see this movie, and they will find exactly what they seek, nothing more but certainly nothing less. It's that nothing more part that ultimately disappoints.
